Composite Doors

A highly secure and efficient entrance for your home

Composite doors from Alpine Glass offer you the ultimate levels of both style and functionality, being highly secure, efficient, and providing you with great aesthetics. Unlike either uPVC or timber doors, composite doors are multilayered to create a door which is thicker, stronger and more robust that its single material counterparts. Operating as a premium installer of Solidor products, strength is our top priority.

Our composite doors are made from a solid timber core which is clad in a GRP skin, making for an extremely strong structure which is not only efficient but highly secure. When combined with our standard deadbolt locking system from Ultion, our composite doors are some of the most secure doors on the market, giving you peace of mind that your property is secure against intrusion.

Their hybrid construction also means that they offer near unparalleled levels of energy efficiency. The solid timber core incorporated into the design of our doors means that they are exceptional thermal retainers, whilst they are also fitted with energy efficient glass as standard. Composite doors from Alpine Glass are the perfect choice for those who prioritise efficiency levels, as they more than exceed current efficiency levels stipulated by building regulations.
